I couldn't find a KSS-272A anywhere either. Ended up buying a lower spec Sony on eBay for €90 that used the same laser (505ES from memory) and then transplanted it into my CDP-X707ES. Not an easy job (only the lasers are the same from lesser models, spin motors different), but I now have a non-skipping 707 again.

I'll be selling it soon - but not sure what it is worth nowadays? Guess it depends on finding someone interested in Sony's battleship engineered players!

Like the laser pickup KSS-190A, KSS-270A, KSS-271A, KSS-272A, KSS-273A/B, KSS-280A, KSS-281A...and the CDM1 pro, mk2, and other early CDM series of laser is hard to find now, since it is out of production for a long while.
if you are a professional DIY, you can try to change the laser tube in it, may be it can be help you

For all you guys with skipping problems. Try ajusting the FCS knob in the right side print - ajust it a bit backwards. Give it a little "contact spray" before doing this, and you might be lucky as I was just 1 hour ago... Picked up a X555ES player from the local flea market, and it was skipping - but not anymore :-))

He is talking about the focus pot just right of the transport when looking from the front. There are 2 pot actually. One is focus and the other is track. DO NOT TOUCH THE TRACK. And yes he does mean counter clockwise. The focus will fix 99% of the problems. CD's and DVD's for that matter move slower the deeper they get into the play list so by adjusting the focus you might solve all of your problems but on some CD's with long play lists as the CD slows the problem may come back up. It is a fine line and when or if that problem does occur you can readjust further counter clockwise but not to much. I to have a 555es and have fixed it that way. Also sometimes CD skips are caused by the clock and not the laser.
